Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a roof of a garage, shed, bus stop and other simple buildings.

(Prior Art) Conventionally, in this type of roof, the supporting member has a groove-shaped cross-section, and an array material in which concave portions and convex portions are alternately provided along the length direction at the upper edge portion and the array material. Is integrated with the girder material that constitutes the frame of the roof by screws, and the roof material is fitted into the concave and convex portions of the array material. (For example, Japanese Utility Model Publication No. 59-7477) (Problems to be solved by the invention) However, in the conventional supporting member for the roof material, since the array material is integrated with the girder material on the site by screws, At the time of construction, the girder material and the array material must be separately attached, which is a workability disadvantage. Further, since the array material is generally made of aluminum and the girder material is made of steel, there is a drawback that the cut ends of the girder material are likely to rust due to cutting on site.

(Means for Solving Problems) As a result of earnest efforts in view of the above-mentioned conventional drawbacks, the present inventor provides a support member for a roof material in which the above-mentioned drawbacks are eliminated.

Hereinafter, the present invention will be described with reference to the drawings.

In the drawing, (A) is a supporting member used for the roof of the present invention, which is manufactured by aluminum extrusion molding. The support member (A) is formed of a girder material (1) and a pair of rising pieces (2).

The girder (1) is a long body having a trapezoidal cross section and a hollow body (11), and at least has strength as a frame for constituting a roof. For example, in the case of Fig. 1, girder material (1)
Is a trapezoidal cross section with a hollow body (11) and a groove (12) is integrated at the lower end along the length of the body (1).
Is not limited to the above as long as it has a trapezoidal cross section and a hollow body, and may have sufficient strength to form a roof.

The pair of rising pieces (2) are integrally provided on the upper end of the girder material (1) in parallel along the length direction at a predetermined interval over the entire length. At the upper edge of the pair of rising pieces (2), a recess (21) on the undercut surface and the recess (2
Convex part (22) that is slightly smaller than the undercut surface of 1)
And are provided alternately. The shapes of the concave portion (21) and the convex portion (22) are such that a roof material (3) described later can be fitted and fixed as shown in FIG.

The roofing material (3) is an elongated panel whose both ends are curved in the same direction and have a groove-shaped cross section. As shown in FIG. 2, the roof material (3) is fitted into the concave portion (21) so that the curved portions at both ends are on the upper side and the outer wall surface is in contact with the convex portion (22). It is fitted so that the wall surfaces are in contact, and the convex part (2
The curved parts at both ends of the roofing material (3) fitted in (2) are
Roof material (3), (3) fitted in recesses (21), (21) adjacent to 2)
It is designed to be fixed by covering the end curved portion of the.

In the supporting member (A) of the present invention, the girder material (1) is fixed directly on the beam overhanging the stanchions that are erected to form a garage, shed, bus stop or other simple building, and the rising piece ( The roof material (3) is used by being fitted into the concave portion (21) and the convex portion (22) of 2).

(Effects of the Invention) As described in detail above, in the roof of the present invention, the supporting member has a trapezoidal cross-section, and a girder member having a hollow body and a predetermined interval along the length direction at the upper end of the girder member. Since it consists of a pair of rising pieces that are integrally provided in parallel, the supporting member has rigidity due to the hollow trunk with a trapezoidal cross section, and it can be used as a roof frame, as well as conventional beams and array materials. It is not necessary to assemble a plurality of members, and it is possible to improve the assembly workability when performing on-site construction.

Further, in the present invention, since the recesses of the undercut surface and the projections having a shape smaller than the undercut surface of the recess are alternately provided along the lengthwise direction at the upper edges of the pair of rising pieces of the support member. An elongated panel-shaped roofing material with both ends curved in the same direction and having a groove-shaped cross section is fitted in the recess so that the outer wall is in contact with the curved end on the upper side. Can be fitted so that the inner wall surfaces thereof come into contact with each other, and the roofing material is firmly supported by being supported at two points in the longitudinal direction by a pair of rising pieces spaced at a predetermined interval.

Furthermore, since the supporting member is integrally formed of the girder material and the rising piece by aluminum extrusion molding, rusting does not occur from the cut end of the girder material due to cutting in the field as in the conventional case.
